Technical field
The utility model relates to a kind of hanger, relates in particular to a kind of structure that adopts the expansion link hanger of Camlock device.
Background technology
In daily life, the various hangers that are seen everywhere, as hang curtain hanger, hang the hanger of shower curtain and hang in the wardrobe of clothing or the hanger on the balcony etc.Because in the wardrobe of each family, the hanger length that needs of bathroom or balcony is generally different, therefore just needs expansion link hanger, the length that can regulate hanger as required.The interior pipe and the fixed form between the outer tube of the expansion link that general expansion link hanger adopts also are various, commonly adopt retainer ring or fixed block extruding outer tube, make outer tube hold interior pipe location tightly, this fixed form is not firm, and the cooperation place is damaged easily, and having used of a specified duration can be difficult to operation because of wearing and tearing.Also have some to adopt the expansion link of Camlock device at present, such as the patent No. is a kind of expansion link locking device of " 200420095269.4 ", comprise outer tube, in pipe and can be socketed in in the pipe and the limit plug that is connected and fixed with interior pipe, the stop edge that an external diameter is slightly less than outer tube diameter is established on limit plug end face limit, stop edge is provided with the rounded biasing post of a section outward, the outer end of biasing post also is provided with the outer stop edge that an external diameter is slightly less than outer tube diameter, sheathed one is " C " shape and rubber-like tensioner ring on the biasing post, its opening is positioned at the thin side of wall thickness, and its middle external tube stage casing also is provided with a constraint groove; Stop edge top margin and biasing post junction are provided with a spacing raised line, and the lower semisection of tensioner ring one side of something also is provided with the breach corresponding with spacing raised line.This structure locking is firm, but complex structure, the manufacturing cost height.
Summary of the invention
It is good that the utility model purpose provides a kind of Camlock device locking effect, and the structure of the expansion link hanger of low cost of manufacture.
The utility model is by the following technical solutions: the structure of expansion link hanger comprises outer tube and is set in interior pipe in the outer tube, the end of interior pipe in outer tube is fixed with the Camlock device, outer tube one end is provided with position limiting structure, the position limiting structure internal diameter is slightly larger than interior external diameter of pipe, the outer tube other end and the interior pipe other end flexibly connect with the hanger fixture respectively, the Camlock device comprises limit body and the snap ring of being with biasing post, limit body is provided with fixed leg, an end of pipe in fixed leg is fixed on, wherein the biasing post of limit body is with respect to fixed leg off-centre, the upper and lower side of biasing post is provided with confined planes, the lower limit plane is connected with fixed leg, bound plane external diameter is slightly less than outer tube diameter, greater than the internal diameter of the position limiting structure of outer tube, snap ring is set on the biasing post, between the bound plane, snap ring opening part wall thickness is thinner, gradually to one side wall thickness thickening relative with opening.
The position limiting structure of above-mentioned outer tube is the pipe of external diameter of pipe in a bit of internal diameter is slightly larger than, or outer tube one end is provided with one or more trim rings, and the outer mouth of pipe inwardly forms bag mouthful, trim ring and inwardly the internal diameter of bag mouthful be slightly larger than interior external diameter of pipe.
Above-mentioned hanger fixture is provided with and extraneous structure and the connecting hole that is connected with outer tube or interior pipe of being connected and fixed.
The outside of above-mentioned outer tube one end position limiting structure is provided with Anti-slip handle.
Above-mentioned interior pipe can be used as the outer tube of pipe in another.
The utility model adopts above structure, does when relatively rotating when interior pipe and outer tube, and the Camlock device rotates with interior pipe, its biasing post is along with rotation, the centrifugal end of biasing post turns to snap ring wall thickness thicker part by snap ring wall thickness thin location, makes snap ring outer wall extruding outer tube inboard, so can lock interior pipe; Do when relatively rotating in the other direction when interior pipe and outer tube, the centrifugal end of biasing post turns to snap ring wall thickness thin location by snap ring wall thickness thicker part, and snap ring no longer pushes the outer tube inboard, so in pipe can be in outer tube telescopic movable up and down.This is simple in structure, and manufacturing cost is lower, but the effect of locking is very good.
